EVAPORATING-PAVN.

SPECIFICATION forming part of Letters Patent No. 517,765, dated- April3, 1 8 94. Application filed October 16, 1893. Serial No. 488,317- (Nomodel.)

To all whom it may concern.-

Be it known that I, SIMEoN ALEXANDER POCHE, a citizen of the UnitedStates, and a resident of Donaldsonville, in the parish of As censionand State of Louisiana, ha'veinvented certain newand useful Improvementsin Evaporating Apparatus; and I do hereby declare that the following isa full, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification.

My invention relates to improvements in boilers for evaporating cane andother juice in the manufacture of sugar, andits object is to provide animproved construction of the same, whereby I secure superior advantageswith respect to economyin fuel andefficiency in operation.

Theinvention consists in thenovel construction. and combination of partshereinafter fully described and claimed.

, In the accompanying drawings: Figure 1 is a central longitudinalsection of a boiler and evaporating pan constructed in accordance withmy invention; on the line 00-05, Fig. 2. Fig. 2 is a cross section ofthe same.

. In the saiddrawings, the reference numeral 1 designates a cylindricalboiler provided with a series of fiues 2,in its lower part connectedwith the heads 3. These fiues can be of any number and size foundconvenient or desirable, five being shown in the present instance.

In the upper part of the boiler is a rectangular opening in which theevaporating pans 4., are located. Three of these pans areillustrated'inthe drawings,but their number may be varied if desired, or circumstancesrequire. These pans as shown, are formed of a rectangular box,projecting down into the boiler a sufficient distance through theopening therein, and are formed with outwardly flaring sides and ends 5'and 5", and divided by means of partitionsffi, into a number ofcompartments which constitute the pans proper.

Passing through these compartments are a number of steam pipes 7 whichcommunicate with the steam space of the boiler, and the bottom of eachcompartment is provided with a draw off pipe 8, having acock 9. Theupper edges of the partitions are formed with.

the pipes 7 which will result in the evaporization of the juicecontained in the pans. From the above it will be seen that the pansthemselves will not only be heated by the steam surrounding the lowerpart thereof, but the liquor contained therein will be heated by thepipes 7 passing therethrough, thus effecting a great economy in fuel.

Having thus described my invention, what I claim is In an evaporatingapparatus, the combination with a boiler having an opening in its upperpart, and provided with a series of fines, of the rectangular box seatedin said opening, having flaring sides and ends, the partitions locatedtherein having troughs in their upper edges and dividing the box into aseries of compartments, the drainage pipeconnected with said troughs,the transverse pipes passing through said compartments and communicatingwith the steam space of the boiler and the ,draw ofi pipes connectedwith said compartments, substantially as described.

In testimony that I claim the foregoing as my-own I have hereuntoaffixed my signature.

in presence of two witnesses.
